Title: D.c. voltage measuring device
Inventor: KISHIMOTO KAZUO
IPC: G08B21/00
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of the detection of disconnection in a burden resistor by connecting in parallel with the burden resistor a neon discharge tube the discharge starting voltage of which the voltage across the terminals of the burden resistor is below when the burden resistor is in normal operation, and making the neon discharge tube generate a voltage above the discharge starting voltage if the burden resistor is disconnected. SOLUTION: A neon discharge tube 7 the discharge starting voltage of which the voltage across the terminals of a burden resistor 2, connected across both the terminals of a direct current source 1, is below when the burden resistor 2 is in normal operation. When the burden resistor 2 is in normal operation, therefore, the neon discharge tube 7 does not start discharge and thus does not light up. If the burden resistor 2 is disconnected, a voltage exceeding the discharge starting voltage is applied to the neon discharge tube 7. Accordingly, the neon discharge tube 7 is actuated and emits light. Further, excessive voltage is prevented by the discharge operation characteristics of the neon discharge tube 7. In a small current range a lighting circuit 8 in parallel connection accumulates the lighting energy of the neon discharge tube 7 and intermittently lights the neon discharge tube 7.

Title: On-load tap changing transformer
Inventor: MATSUMOTO HIROKAZU
IPC: H01F29/04
Filed: 1986-08-14
Abstract: PURPOSE:To prevent the scattering of metallic powder, and to obviate the generation of the accident of breakdown by covering fixed and movable contacts for a tap selector with a cylinder with a bottom in a tank and circulating an insulating medium in the cylinder into the tank through a piping and a filter. CONSTITUTION:Since metallic powder generated from a tap selector 3d scatters in an insulating gas first but it is surrounded by a cylinder 7, scattering toward the transformer content 2 side is prevented, and metallic powder collects on a bottom 8. When an air blower 10 is operated periodically after the number of tap changing reaches a fixed value, the insulating gas 4 in the cylinder 7 is sucked from an inlet port 13, and blown against the tap selector 3d from a blow-off port 14 through a piping 9. Consequently, metallic powder is sucked into the piping 9 from the inlet port 13, and the greater part of metallic powder are collected by a filter 11 while the cleaned insulating gas 4 is blown against the tap selector 3d in the cylinder 7 from the blow-off port 14 again. Accordingly, metallic powder is captured quickly by the filter 11 without scattering in a tank 1.
